Zorocrates pictus Simon figures 32–36 ; map 3

Zorocrates pictus Simon, 1895b: 107 (female holotype from Baja California, should be in MNHN, lost).

NOTE: The only specimen currently in the vial that should contain the type of this species is a misplaced crab spider. We use the name here for the only species other than Z. badius that is known from Baja California .

DIAGNOSIS: Specimens resemble those of Z. badius but can be distinguished by the distally narrower retrolateral tibial apophysis of males ( figs. 33, 34 ) and the smaller epigynal midpiece of females ( fig. 35 ).

MALE: Total length 8. Coloration as in Z. badius . Leg spination: femora: I p0-1-2, r1-1-2; II p0-0-1, r0-0-1; III p0-1-1; IV r0-1-2; patellae IV r0-1-0; tibiae: I d0-0-0, p0-1-0, r0-0-0; II d0- 0-0, p0-1-1, v4-2-2, r0-0-0; III r1-0-1; IV d1-1- 1; metatarsi: I p0-1-0, r0-1-0; II p1-1-2, r0-0-0; III r1-1-2. Cribellum present. Retrolateral tibial apophysis long, not widened distally, with low proximal ledge; median apophysis elongated, oriented obliquely, widened at middle; tegular apophysis laterally flattened ( figs. 32–34 ).

Map 3. Records of the Zorocrates alternatus , badius , and chiapa groups. Z. alternatus group: Z. alternatus (dots), Z. huatusco (circle), Z. colima (diamond). Z. badius group: Z. pictus (dots), Z. badius (circles), Z. blas (filled squares), Z. chamela (open square), Z. bosencheve (filled triangles), Z. contreras (open triangle). Z. chiapa group: Z. chiapa (circles), Z. chamula (dots).

FEMALE: Total length 10. Coloration as in male. Leg spination: femora: I d1-1-0, p0-0-2, r0-0-0; II d1-1-0, p0-0-1, r0-0-0; III p0-1-2, r0- 1-1; IV p2-0-1, r0-0-1; patellae IV r0-1-0; tibiae: I d0-0-0, p0-0-0, r0-0-0; II d0-0-0, p0- 1-0, v3-2-2, r0-0-0; III r1-0-1; IV d1-1-1; metatarsi: I, II p0-0-1, v2-2-2, r0-0-0; III r1- 2-2. Cribellum present. Epigynal septum relatively short, without elevated anterior hood; spermathecal ducts wide ( figs. 35, 36 ).
